Very nicely put and to the point. You'd be surprised at where you can make up a 1/2" and under if you try...;-)

Replacing a Shut Off Valve


I am replacing a shut off valve that's developed a small leak. I bought a replacement that fit to my pipe size. It didn't occure to me until after I tried to put it on that it has less reach than the old one. Basically, it reaches about an 2/8 of an inch shy of the other one so I can't get the nut to grab it. How do pros usually handle these discrepency?

Pipe Stretcher...

Seriously, worst case is that you may have to cut in a small nipple to extend to length. If copper, a "repair coupling" is used. It is a regular coupling without an internal "stop" or dimple so it slides entirely on to the starting pipe, then slides back over the added pipe before soldering.

If screwed pipe (yup, there is a reason they call it screwed!) you may have to cut in a new threaded nipple and union to the length that you need.

But, you know what I would do first? Given that it is only 2/8 of an inch (you missed the reducing fractions class like I did, didn't you?) try this:

Walk back along the lengths of pipe and see if you cannot loosen up a couple of clamps or hangers just to slide the pipe along it's length. If it is some distance to the next elbows, you should be able to walk the pipe along to make up the difference without putting significant stress on the next joints. A little muscle as Bob suggests.

If that seems too tough, you will have to cut in a new nipple.

a hair ??

if you are only shy 1/16 " a little muscle should solve the problem.

Two words......

"Extention Coupling"

If its screwed pipe and its just a little bit, go to a real supply house and buy an extention coupling. Its a little fitting thats male on one end, female on the other and very short.

Done lots of retrofits and used lots of these. kinda hard to find now days.

valve job

I gotta ask this one (g) Unless you had a l&r valve, what did you remove first? Break a union, & back off a piece of pipe or a nip? Maybe a four wheeler, or electrically operated recip saw. Or just get out the ole hack saw, and use the armstrong method of removal? If any of the last three, then maybe (God forgive me) a dresser? A quick fix for the H.O. BWDIK,IJAP

I was going to say

aren't they hard to find nowadays? And there you said it!

Where can you get them if not salvaged? Dang. Those Deadmen had it easy. 10 inch threaded pipe, catching a thread twelve feet in the air... extention couplings... ah those were the days...
